Yeah I tried that didn't work, but my friend just phoned me saying it's working now after a fully charged battery, I thought it was very strange it had about 60% on it

Try to remove the batterij for like 2 min. and put it back in. Start the phone, hopefully it works again. However this is the second time I got this problem (with the stock rom). I kinda hate Samsung right now.

Screen dims, but never shuts off

I just noticed this morning that when I hit the power button the screen only dims now. I swear it used to shut off the display completely before today, and I know for certain that is how it worked on 1.6. This really is annoying, because now when I put it in my pocket the 3 buttons are constantly being depresses and they vibrate, which lights the display again. That coupled with this stupid lock screen that I have to try to open 3-4 times is really making me angry. Maybe it's just me thugh.....
I'm assuming you upgraded to 2.1?
I remember reading somewhere that someone had a similar issue after upgrading to 2.1 but then they re flashed 2.1 a different way and problem went away.
Same issue here, it really eats up my battery life, and I do end up pushing those soft keys all-too often... I am on 2.1 and that is definitely when the problem started, I'm going to try reflashing to see if I can eliminate the issue.
try the steps found here on streaksmart.com. She reports that she has no issues when its done that way. I don't have my streak yet but will follow these steps when i get it.
I had a similar problem before, only the screen would go off and on again and stay on!
Turns out it was an APP that done this.
It is possible an app is causing the problem.
Don't leave wifi on when not using and the problem disappears.

I've been experimenting with what's been causing this on mine, and I noticed that sometimes wifi will not shut all the way off. It hangs at "Turning off..."
So I tried not letting it sleep with wifi on, I turn it on if I need it, then turn it off (really a big pain in the butt) but went two days with no "no sleep" problems.
Today I tried leaving wifi on all the time, not two hours later it happened.
Since it's not happening to everybody, I wonder if it has something to do with our wifi setups. Maybe the router brand, or the encryption type, or something?
Last night I powered off the phone before better. I have wifi on all the time and I never shut it off. Today though, I have had no issues with the sleep function. It's still mid afternoon so we'll see if it continues this way. If so I will explore the wifi solution as well.
I was having this problem and somehow this setting was wrong:
SETTINGS>>APPLICATIONS>>DEVELOPMENT>>STAY AWAKE
mine was checked and we all know what that mean. Check yours to be sure if your not up for flashing again. Just a thought in case you overlooked this...

Yes, it means the screen will not time out and go off when it's being charged, but you can still turn it off, and mine wasn't plugged in when I couldn't turn it off.
I don't think this is related to what I've been seeing, but thanks.
It seems that Bluetooth did it today. I was fine all day going black on sleep with power button, but once I switched on wireless to connect to my car stereo it never went off again. Even if I turn off the wireless I have to shut down and reboot.

Same here. Started car and it showed zero signal strength for the phone on the dashboard display. Pressed the power button on the Dell Streak and the car display then displayed the signal strength. From then on, the screen would dim but not shut off.

Was your wifi also enabled (even if not connected to any AP's) when this happened?

Yes, and I couldn't turn it off once the "screen dim bug" took hold. Today I've rebooted and left Bluetooth OFF and Wireless ON and have not had an issue all day long, and that's making calls, using 3G, wireless and running a pile of apps. I think I can live with no Bluetooth until the next release.

I don't think it's BT. I think it's wifi not recovering properly from sleep mode.

Fair call. However, I've now had BT off for 6 hours and I'm using 3G, wireless and USB transfers and it hasn't hiccuped yet. This is the longest I've had with no screen dim bug.
I did notice that when I walked out to the car, the Streak could still "see" my home wireless network, then starting the car and the BT pairing and connecting is when the screen dim bug came back.
Maybe it's when both are run at the same time and both are connected/paired?

I agree its looks like its a wifi issue. I always keep my bluetooth off and it still did it.
I got mine fixed... but the problem is i did a bunch of steps and now cant figure out which one actually fixed it. its been running great for 12hrs now.
What I did, since I noticed that wifi sometimes didn't sleep or wake itself up properly all the time (which i think is what's affecting our Streak sleeping), was turn off the wifi sleep. In other words when my device shuts off wifi stays active.
However, I then used "Tasker" from the Market and setup two profiles. When the screen goes off it shuts off 3G, wifi and autosync. Then when the screen comes on it turns on 3g/wifi, waits 20 secs and enables autosync (which then initiates a mail/calendar/contacts sync).
This has worked perfectly, and I get mad good battery life to boot. Now this means I don't get mail/updates (facebook, weather, etc - still get calls and txts obviously) but for me it's not a big deal especially for the battery life.
I may eventually setup more Tasker events to duplicate "Juice Defender" and poll every half hour (3G only, when screen is off only) to get my updates, but for now it's been working great.
I also setup profiles so if I'm not where I have wifi pairings it shuts down wifi. Also if it detects I'm connected via wifi (at home for instance) it disables my lock screen. I also have it set to only start GPS for apps that need it (Maps, Navigation, Places, etc) and that helps save battery too.
Tasker is an awesome app for $3.99. It has a steep learning curve, but there are enough walk-throughs available to teach you how to do the basics.

Found the fix on Modaco. Have a look at the last page of the thread called "2.1 Bugs ....., Add what you find please....."
I never knew there was an "Advanced" menu for WiFi!
yeah that is not it. I also have mine set to never time out so does that mean it will never shut off either? Anyway, it keeps happening through the day. Wifi and bluetooth do seem to have something to do with it, but I need them both on all the time so the only thing I can do is reboot. Then it is good for a couple hours. Are the any apps that have a reboot? That's one thing I miss on the iPhone.

i905 Wi-Fi won't turn on!!!

Hey guys,
My aunt asked me over to help her installing her S4. I did all the things she asked and after I explained some stuff like the tiles (Wi-Fi had been on all time). So I pressed the Wi-Fi tile on and off. After I turned it off, it just wouldn't turn on. When I go to the Wi-Fi menu it shows it is turning on and off. After a while it just stays off and won't try to turn itself on again. It is just stuck in some kind of a loop...
My aunt told me she had exactly the same problem a few days ago and went back to the shop, but before she could be helped the Wi-Fi started working again. I tried turning the phone on and off (dohh!) and reinstalled the latest firmware through samsung KIES, nothing worked. This phone isn't rooted or anything, just out of the box.
My attachment shows what servicemode says @ wi-fi
Could anybody help/advice me please?
Thanks in advantage!
Try factory reseting it

Hey guys, thanks for replying. I turned the phone off overnight and wi-fi started working again after I turned it on, I had the same problem again this morning when I switched the tile on and off after downloading navigon maps and set it again off for 30 minutes. Now it works again. So weird, but I'm glad I'm having an HTC One S , no just kidding ,the s4 is marvellous

Wi-fi is bricked

Ok, so my phone has this problem where it keeps turning on and off randomly, which I think is now known is an issue with some LG G2's and you know I hate it but I guesss I can live with it. Even though if any of you have a solution for that please tell me. But now one time when it turned off and then powered back on, the wifi stopped working. I don't mean my network, I mean the actual wifi on my phone. When I scroll down my notification bar, the wifi logo is grey but it's flashing, like it usually does when you turn it on, but it doesn't turn blue. When I got to the wifi section on my setting, the on and off switch is greyed out (but faintly blue, even though you can't touch it), and when I tap on the wifi section itself, it just says "wifi turning on.." HELP PLEASE

re flash the rom. i have things happened like that before, wiping all and flashing another rom fix, or go back to stock, sometimes the options settings are grey out. that fixes it.
